A man and woman are expected in federal court in Charleston this week on charges related to skimming devices found on gas pumps in the Lowcountry and all along the I-95 corridor.

The U.S. Secret Service has now taken over the investigation as law enforcement agencies work to narrow down the number of cases to which the two could be connected.

Alberto Yordan, 46 of Hialea, Florida and Katty Rios Lopez of Brooklyn, New York each face charges of possession of two or more cards issued to other persons and financial transaction card forgery. They were taken into custody Thursday by officers with the Yemassee Police Department.

Matthew Garnes, public information officer for the Yemassee Police Department said officers stopped a vehicle the two were riding in for a traffic violation. Following a search, Garnes said officers found a "large sum of cash ($34,434), credit cards with various names, credit card skimmers..."

An affidavit states the two had 38 credit cards in their possession. It also states Rios Lopez had $3,472 and an Ecuadorian passport in her purse. Also in her possession, investigators say, were credit cards wrapped in a Victoria's Secret receipt. Investigators pulled video from the Victoria's Secret store listed, and say surveillance shows Rios Lopez and Yordan in the business together on the date stamped on the proof of purchase.

The same affidavit states Yordan was asked about his primary means of employment, and he responded, "working the credit cards."

Credit card skimmers were found on Hardeville gas stations last week, which is about 40 miles south of Yemassee. Garnes said those devices were connected by investigators to Yordan and Rios Lopez by local agencies and investigators with the FBI.

Yordan and Rios Lopez were transported to the Al Cannon Detention Center this week ahead of an expected federal hearing. Sources close to the investigation say the number of cases the to which they are connected is large.
